Description:

common abstract superclass for TCP socket servers
(like FTPServer and others).
Only handles connection setup and session startup.
Does not implement any concrete protocol - this must be done in the session instance.

    (FTPServer forPort:12345)
        sessionClass:SmalltalkFTPSession;
        start
